I don't believe so, no. The main features I can think of are: * Various power/performance optimizations. * Various IO controllers on newer chips (such as SATA, Tegra124 PCIe, USB3), although there are patches sent for all of these now. NOR flash, I2C/SPI slave mode, one-wire, perhaps a few other minor IO controllers. * Various features in supported IO controllers (e.g. high-speed eMMC/SD modes, USB2 bus suspend, ...) * USB device mode. -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
